Discrimination and Workers' Expectations

The paper explores the role of workers' expectations as am original explanation for the puzzling long run persistence of discrimination against some minorities in the labor market. A game of incomplete information is presented, showing that ex ante identical groups of workers may be characterized by unequal outcomes in equilibrium due to their different beliefs, even though discriminatory tastes and statistical discrimination by employers have disappeared. Wrong beliefs of being discriminated against are self-confirming in this circumstance, being the ultimate cause of a lower percentage of promotions which supports these wrong beliefs.discrimination, workers' expectations, self-confirming beliefs

Costless Discrimination and Unequal Achievements in a Labour Market Experiment

We investigate the emergence of discrimination in an experiment where individuals affiliated to different groups compete for a monetary prize, submitting independent bids to an auctioneer. The auctioneer receives perfect information about the bids (i.e. there is no statistical discrimination), and she has no monetary incentive to favour the members of her own group (the bidders are symmetric). We observe nonetheless some discrimination by auctioneers, who tend to assign the prize more frequently to a member of their own group when two or more players put forward the highest bid. Out-group bidders react to this bias and reduce significantly their bids, causing an average decay of their earnings throughout the game, with cumulative effects that generate strongly unequal outcomes. Because the initial bias is costless, such mechanism can survive even in competitive market, providing a rationale for a well-known puzzle in the literature, i.e. the long-run persistence of discrimination.discrimination, tournament, groups, experiment

Family Background, Self-Confidence and Economic Outcomes

In this paper we analyze the role played by self-confidence, modeled as beliefs about one's ability, in shaping task choices. We propose a model in which fully rational agents exploit all the available information to update their beliefs using Bayes' rule, eventually learning their true type. We show that when the learning process does not convergence quickly to the true ability level, even small differences in initial confidence can result in diverging patterns of human capital accumulation between otherwise identical individuals. As long as inital differences in the level of self-confidence are correlated with the socioeconomic background (as a large body of empirical evidence suggests), self-confidence turns out to be a channel through which education and earnings inequalities are transmitted across generations. Our theory suggests that cognitive tests should take place as early as possible, in order to avoid that systematic differences in self-confidence among equally talented people lead to the emergence of gaps in the accumulation of human capital.self-confidence, family background

Gender differences in risk attitudes

Many experimental studies and surveys have shown that women consistently display more risk-averse behavior than men when confronted with decisions involving risk. These differences in risk preferences, when combined with gender differences in other behavioral traits, such as fondness for competition, have been used to explain important phenomena in labor and financial markets. Recent evidence has challenged this consensus, however, finding gender differences in risk attitudes to be smaller than previously thought and showing greater heterogeneity of results depending on the method used to measure risk aversion

Can workers' expectations account for the persistence of discrimination?

The paper explains how workers' expectations of being discriminated against can be self-confirming, accounting for the persistence of unequal outcomes in the labour market even beyond the causes that originally generated them. The theoretical framework used is a two-stage game of incomplete information in which one employer promotes only one among two workers after having observed their productivity, which is used as a signal of their ability. Workers who expect to be discriminated against exert a lower effort on average, because of a lower expected return, thereby being promoted less frequently even by unbiased employers. This implies that achievements of minority groups may not improve when the fraction of discriminatory employers actually decreases, and such a mechanism is robust both to trial work periods and to affirmative actions like quotas

Discrimination and Workers' Expectations: Experimental Evidence

This paper is an experimental analysis of the role played by workers? expectations in explaining the puzzling long-run persistence of observed discrimination against certain minorities in the labor market. The experiment provides some evidence supporting the theoretical prediction that unequal outcomes may emerge due to disadvantaged workers? wrong expectations of being discriminated against. However, this effect is not long-lasting, since players learn the true state of nature in later stages of the experiment, failing to generate a Self-Confirming Equilibrium driven by wrong beliefs. The strategy method provides additional evidence that expectations matter

Should You Compete or Cooperate with Your Schoolmates?

Building upon some education studies finding that cooperative behaviour in class yields better achievements among students, this paper presents a simple model showing that free riding incentives lead to an insufficient degree of cooperation between schoolmates, which in turn decreases the overall achievement. A cooperative learning approach may instead emerge when competitive behaviour is negatively evaluated by schoolmates, especially when the class is more homogeneous in terms of students’ characteristics (e.g., ability). Empirical evidence supporting our model is found using the 2003 wave of the OECD Programme for International Student Assessment (PISA) survey on students’ literacy levels. A competitive learning approach has a positive individual return (higher in comprehensive educational systems), while student performance increases with the average cooperative behaviour, particularly in tracked educational systems.cooperation, competition, PISA, student attitudes

The Sound of Others: Surprising Evidence of Conformist Behavior

It has been shown that subjects tend to follow others' behavior even when the external signals are uninformative. In this paper we go one step further, showing that conformism occurs even when the choices of others are not even presented to the subjects, but just indirectly perceived. We use the "Click" version of the Bomb Risk Elicitation Task, in which subjects can infer the behavior of others only from the mass of clicks heard. This signal is payoff-irrelevant and largely uninformative about the actual choices of the other participants. Moreover, it is never mentioned in the instructions and therefore it must be spontaneously (and possibly unconsciously) perceived in order to be used. We control the exposure of subjects to clicks by implementing treatments with and without earmuffs. Moreover, we test whether the introduction of a minimal form of commonality, i.e., facing a common rather than individual resolution of uncertainty, makes conformism more likely to emerge. We find strong evidence of conformist behavior even in such an adverse environment. Simply hearing the others clicking affects subjects' behavior. Introducing a common random draw results in a further dramatic shift of the average choices, in particular by women

Gender Wage Gap in Expectations and Realizations

This paper explores the extent to which the gender wage gap is anticipated by workers' expectations. Data collected among second year students of Bocconi University convey information about their wage expectations. Detailed controls allow a clean matching with a sample of Bocconi graduates providing information about their actual wages. The evidence shows that the gender gap implied by students' expectations one year after graduation is consistent with the gender gap implied by the earnings of their elder counterparts. There is instead a misperception of the gender gap later in the career after graduation because students expect the gender gap to be roughly constant while realizations indicate an increasing gap with experience, particularly for the relatively less skilled worker. There is also evidence that the gender gap at the beginning of a career is particularly high in the most recent cohorts and lower in the previous ones. Finally, our results suggest that the careers of females are characterized by "glass ceilings" in particular at high skill levels, and by "sticky floors" at the opposite end of the skill spectrum
